Following pre-training with everyday objects, 8 children aged from 2 to 4 years learned to produce one manual sign (fists placed one above the other, in front of body) to one stimulus and an alternative manual sign (shoulders touched with ipsilateral hands) to the other stimulus, with each of three pairs of different arbitrary wooden shapes (Set 1). The six stimuli then were presented in category match-to-sample tests, which all subjects passed. Three of the children were next trained to produce the manual signs (denoted as fist/shoulder) for an additional six arbitrary stimuli, Set 2. All 3 children went on to pass category match-to-sample tests for Set 2, and for Set 1 and Set 2 combined. In the final experimental phase, 2 of the children were trained, for one of the six stimulus pairs, to produce the vocal tact "zag" to one stimulus and "vek" to the other. Both children showed category transfer of these vocalizations in test trials with each of the remaining five stimulus pairs, and all the stimuli combined in a 12-stimulus array. In line with Horne and Lowe's (1996) naming account, manual sign naming was found to be as effective as vocal naming in establishing arbitrary stimulus categorization, measured in terms of category sorting and transfer of function. The findings also have implications for the training of verbal repertoires in people with learning disabilities. 相似文献

Relational semantics, given by Kripke frames, play an essential role in the study of modal and intuitionistic logic. In [4] it is shown that the theory of relational semantics is also available in the more general setting of substructural logic, at least in an algebraic guise. Building on these ideas, in [5] a type of frames is described which generalise Kripke frames and provide semantics for substructural logics in a purely relational form.In this paper we study full linear logic from an algebraic point of view. The main additional hurdle is the exponential. We analyse this operation algebraically and use canonical extensions to obtain relational semantics. Thus, we extend the work in [4], [5] and use their approach to obtain relational semantics for full linear logic. Hereby we illustrate the strength of using canonical extension to retrieve relational semantics: it allows a modular and uniform treatment of additional operations and axioms.Traditionally, so-called phase semantics are used as models for (provability in) linear logic [8]. These have the drawback that, contrary to our approach, they do not allow a modular treatment of additional axioms. However, the two approaches are related, as we will explain. 相似文献

A relatively large literature has demonstrated that sexual orientation can be judged accurately from a variety of minimal cues, including facial appearance. Untested in this work, however, is the influence that individual differences in prejudice against gays and lesbians may exert upon perceivers’ judgments. Here, we report the results of a meta-analysis of 23 unpublished studies testing the relationship between anti-gay bias and the categorization of sexual orientation from faces. Aggregating data from multiple measures of bias using a variety of methods in three different countries over a period of 8 years, we found a small but significant negative relationship between accuracy and prejudice that was homogeneous across the samples tested. Thus, individuals reporting higher levels of anti-gay bias appear to be less accurate judges of sexual orientation. 相似文献

Research on psychopathy and aggression in women is limited, especially relational aggression (RA). Studies on youth suggest unique associations between RA and callous–unemotional (C–U) traits (e.g., Frick & White, 2008). However, the role of C–U traits in adult RA remains unexamined, particularly functional subtypes of RA (reactive, proactive). Empathy deficits are associated with C–U traits and heightened RA. Based on prior work, we hypothesized that in young women, callous and uncaring tendencies would be related to proactive RA and to a lesser extent reactive RA, and that these relationships would be mediated by cognitive empathy deficits. Hypotheses were partially supported. Callous and uncaring traits were associated with proactive RA, and less so to reactive RA, and the latter association was mediated by cognitive empathy. Unemotional traits were not uniquely associated with RA. Study limitations and implications are considered. 相似文献

This study reports findings and policy recommendations from a research project that applied a relational resilience framework to a study of 60 sole parent families in New Zealand, with approximately equal numbers of Māori, Pacific, and European (White) participants. The sole parent families involved were already known to be resilient and the study focused on identifying the relationships and strategies underlying the achievement and maintenance of their resilience. The study was carried out to provide an evidence base for the development and implementation of policies and interventions to both support sole parent families who have achieved resilience and assist those who struggle to do so. The three populations shared many similarities in their pathways to becoming sole parents and the challenges they faced as sole parents. The coping strategies underlying their demonstrated resilience were also broadly similar, but the ways in which they were carried out did vary in a manner that particularly reflected cultural practices in terms of their reliance upon extended family‐based support or support from outside the family. The commonalities support the appropriateness of the common conceptual framework used, whereas the differences underline the importance of developing nuanced policy responses that take into account cultural differences between the various populations to which policy initiatives are directed. 相似文献

The investigation of visual categorization has recently been aided by the introduction of deep convolutional neural networks (CNNs), which achieve unprecedented accuracy in picture classification after extensive training. Even if the architecture of CNNs is inspired by the organization of the visual brain, the similarity between CNN and human visual processing remains unclear. Here, we investigated this issue by engaging humans and CNNs in a two-class visual categorization task. To this end, pictures containing animals or vehicles were modified to contain only low/high spatial frequency (HSF) information, or were scrambled in the phase of the spatial frequency spectrum. For all types of degradation, accuracy increased as degradation was reduced for both humans and CNNs; however, the thresholds for accurate categorization varied between humans and CNNs. More remarkable differences were observed for HSF information compared to the other two types of degradation, both in terms of overall accuracy and image-level agreement between humans and CNNs. The difficulty with which the CNNs were shown to categorize high-passed natural scenes was reduced by picture whitening, a procedure which is inspired by how visual systems process natural images. The results are discussed concerning the adaptation to regularities in the visual environment (scene statistics); if the visual characteristics of the environment are not learned by CNNs, their visual categorization may depend only on a subset of the visual information on which humans rely, for example, on low spatial frequency information. 相似文献

Previous work suggests that the experiences of online and offline self-disclosure are heterogeneous among individuals. Yet little work has been done to identify the moderating role of individual characteristics and pre-existing relationship characteristics on the diverse relational outcomes. The present study using a 7-day diary design examined whether individuals' self-esteem level and relational closeness would moderate the relationships between online and offline self-disclosure to offline friends and two relational outcomes, that is, relationship satisfaction and trust in friendships. The analyses on 686 diary responses from 98 participants revealed that offline self-disclosure generally predicted greater relationship satisfaction and trust in friendships, whereas the role of online self-disclosure was not statistically significant. More importantly, self-esteem moderated the pattern associated with offline self-disclosure but not that with online self-disclosure. Specifically, offline self-disclosure predicted greater benefits to people with lower self-esteem relative to people with higher self-esteem. Moreover, pre-existing relational closeness moderated the relationship between offline self-disclosure and trust in friendships such that casual friendships benefited more from offline self-disclosure than close friendships did. The present study highlights the importance of personal characteristics and relationship characteristics in understanding the heterogeneous relational influence of different communication modes. 相似文献

IntroductionThe health crisis that France has experienced since the beginning of 2020 has justified the introduction of new health rules requiring changes in behaviour. The context of the implementation of these health rules, instituted very recently and for a limited period of time, raises the question of their perception and respect among the population.ObjectiveMobilising the social developmental psychology, the objective of this article is to explore inter-individual differences in the perception of these health rules measured through the wearing of masks. It aims also at studying the links between these perceptions with the experience of the health context and the perception of other legal public health rules, apprehended through some road safety rules.MethodThe questionnaire survey, carried out during the second confinement with a representative sample of 4999 people, made it possible to measure the experience of the health context, the internalisation of the rules and their justifications, the usefulness of the rules and the perception of the legal system.ResultsThe results show the links between internalisation, the type of arguments used to justify it for wearing a mask and for road rules respectively, as well as the links between internalisation and the perception of the legal system. They also show that women use moral and prudential arguments more to justify their internalisation of rules and that they have internalised the traffic rules (but not the wearing of masks) more than men.ConclusionThese results show that the perception of the rule of wearing a mask is more related to the general perception that individuals have of the legal system and other legal public health rules involving the relationship with others than to the context in which these rules were put in place. 相似文献
